Answer:
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
Step-by-step explanation:
First of all we'll define rational numbers.
A number that can be written in the form p/q where p and q are integers and q≠0 is called a rational number.
Now we have to check if 
is rational or not, we will check if it can be written in the form p/q
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
Answer:
$84.75
Step-by-step explanation:
Given that she earns $9.75 per hour plus 10% of the parking fees that are collected, her income is of 2 folds; an hourly rate and an amount collected based rate.
If the shift is for 5 hours, her income based on
Hourly rate = 5 * $9.75
= $48.75
The amount collected based rate
= 10% * $360
= 10/100 * $360
= $36
Her total earnings will be
= $48.75 + $36
= $84.75
If it is a triangle it would be 149
Answer:
Step-by-step explanation:
5+ 3(у- 4) = 5(y+2) - у
(expand)
5 + 3y - 12= 5y + 10 -y
(combine like terms)
3y - 7= 4y + 10
(move the variables to one side)
-7 = 4y - 3y + 10
(move numbers to one side)
-7 - 10= 4y - 3y
(simplify)
-17 = y or y = -17
I hope this helps!
